* Gets the maximum value of `collection`. If `collection` is empty or falsey
* `-Infinity` is returned. If an iteratee function is provided it's invoked
* for each value in `collection` to generate the criterion by which the value
* is ranked. The `iteratee` is bound to `thisArg` and invoked with three
* arguments: (value, index, collection).
*
* If a property name is provided for `iteratee` the created `_.property`
* style callback returns the property value of the given element.
*
* If a value is also provided for `thisArg` the created `_.matchesProperty`
* style callback returns `true` for elements that have a matching property
* value, else `false`.
*
* If an object is provided for `iteratee` the created `_.matches` style
* callback returns `true` for elements that have the properties of the given
* object, else `false`.
*
* @static
* @memberOf _
* @category Math
* @param {Array|Object|string} collection The collection to iterate over.
* @param {Function|Object|string} [iteratee] The function invoked per iteration.
* @param {*} [thisArg] The `this` binding of `iteratee`.
* @returns {*} Returns the maximum value.
* @example
*
* _.max([4, 2, 8, 6]);
* // => 8
*
* _.max([]);
* // => -Infinity
*
* var users = [

*
* _.max(users, function(chr) {
* return chr.age;
* });
* // => { 'user': 'fred', 'age': 40 }

* // using the `_.property` callback shorthand
* _.max(users, 'age');
